Auck­land War Me­mo­rial Mu­seum

Element - - Ecology -

Sit­ting amid the serene sur­round­ings of Auck­land Do­main, the Auck­land War Me­mo­rial Mu­seum is an im­pres­sive struc­ture re­garded as one of the finest her­itage build­ings in the coun­try and now the first mu­seum in the world to achieve CE­MARS cer­ti­fi­ca­tion (Cer­ti­fied Emis­sions Mea­sure­ment And Re­duc­tion Scheme). The mu­seum’s sus­tain­abil­ity en­gi­neer, Karl Satchell, says cer­ti­fi­ca­tion was sought to get an in­de­pen­dent au­dited bench­mark of the mu­seum’s green­house gas foot­print. Built in 1929, with ad­di­tions made over the years, it had be­come an en­ergy hun­gry op­er­a­tion through ef­forts to pro­vide the sta­ble tem­per­a­tures and hu­mid­ity re­quired to pre­serve thetaonga (mu­seum trea­sures). Its orig­i­nal de­sign to be nat­u­rally ven­ti­lated re­sulted in air in­fil­tra­tion; which ef­fec­tively meant the mu­seum was push­ing out con­di­tioned air to the rest of Auck­land and con­tribut­ing to its hefty $1mil­lion a year en­ergy bill. “It was a wind tun­nel, pos­i­tive air pres­sure at one end, neg­a­tive pres­sure at the other end,” says the mu­seum’s build­ing fa­cil­i­ties man­ager John Glen. “We also had em­bed­ded prob­lems with our air-con­di­tion­ing en­ergy con­trol sys­tems.” Fol­low­ing an en­ergy au­dit – sup­ported by the En­ergy Ef­fi­ciency & Con­ser­va­tion Au­thor­ity (EECA) and un­der CE­MARS – a glob­ally recog­nised scheme – the mu­seum ini­tially com­mit­ted to re­duc­ing its car­bon foot­print by 5 per cent over five years. But with changes to en­ergy sys­tems and the in­tro­duc­tion of hi-tech me­ters and mon­i­tor­ing fea­tures, it’s al­ready well ex­ceeded its tar­get in the first year. Glen now pre­dicts they can achieve a 20 per cent re­duc­tion. In full, the over­haul has led to more con­vivial spa­ces for the in­quis­i­tive, con­sid­er­able sav­ings and a new sus­tain­able con­science – one which Glen says is now fun­da­men­tal to how the mu­seum moves for­ward.
